请教个176 E-LODGE的问题

nodder

我是由SA担保的
在移民局E-LODGE 176的时候需要选择是哪个AGENCY担保的
我看SA的选项有2个，一个是SA-Immigration South Australia
一个是SA-DEPARTMENT OF TRADE AND ECONOMIC DEVELOPMENT

而我看我的担保函上的落款是
Manager - General Skilled Migration
Immigration South Australia
DEPARTMENT OF TRADE AND ECONOMIC DEVELOPMENT
Email: gsm.sa@sa.gov.au
Website: www.migration.sa.gov.au – Migrate from Overseas

这个两个选项都有，请问到底该选哪一个呢？
